But which one do you guys think will best suit my theed palace recreation from EAs battlefront 2 ?The palace floor looks like it’s made of marble so it’s kinda glossy. what should I do with my model to acheaive this look.

I would use specular only for the palace floor. Then make the floor semi-transparent. When using both specular and transparency, the alpha layer of your .tga will be interpreted as an alpha map for transparency instead of a specular map, so the strength of the specular can only be adjusted through the specular decay value.

Finally, copy the entire palace interior and turn it upside-down in order to create the same reflection effect used with certain Death Star hallways and even the rotunda from stock Naboo.
